To all'whom, it may concern.-

Be it known that 1, JAMES M. SINCLAIR, of New York city, in the county and State of New York, have invented a new and useful Improvement in Partitionans, of which the following is a full, clear, and exact description. I

My invention relates to an improvement in partition-walls, and has for its object to provide a means whereby apartition-wallfireproof, if desired may be conveniently and expeditiously erected in any room, and quickly and easily removed without injury to the side walls or to the ceiling.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters and figures of referviews.

Figure 1 is a partial interior view of a room divided into sub-compartments by my improved partition. Fig. 2 is a perspective view of a panel employed in connection with the partition. Fig. 3 is a central vertical section partition, the panels upon one side b eing removed. Fig. 4 is a perspective view of apor- Fig. 5 is a perspective view of one of the tie or panel bars. Fig. 5 is a partial perspective view of the inner side of one of the face-plates. Fig. 6 is a transverse section on line 6 6 of Fig. 3, with the panels removed. Fig. 7 is a partial front elevation of the partition when ornamental panels are employed. Fig. 8 is a section taken section on line 9 9 of Figs. 7 and 8.

In carrying out the invention the uprights or standards A of the partition consist of two pairs 10 and 11 of angle-irons placed face to face a suitable distance apart, the irons of each pair being so placed that the longitudinal edges of one of their members will constitute the outer faces, and the sides of the other members the inner faces, as best shown in Figs. at and 6. Each pair of angle-irons is connected by a series of transverse T-irons or braces 12, preferably arranged at intervals apart corresponding to the height of the panels to be employed in the construction of the partition. The horizontal members of the T-irons are placed uppermost, whereby a fiatbearing-surface a, is obtained between the opposed pairs of angle-irons forming the standards, and the upper horizontal members of the T-irons are sufficiently cut away to permit the extremities of the webs or vertical members to pass between the opposed outer members of each pair of angle-irons, as shown in Fig. 6, the T irons or braces being secured to the angle irons by suitable screwbolts or rivets. These standards or uprights A may be constructed in a shop, the height of the ceiling being known, and carried in a convenient state to the building in which the partitions are to be erected.

When the standards have been 'placed in position at suitable intervals apart, a longitudinal base strip or strips 13 are secured to the upper or bearing surfaces of the lower T irons or braces 12, as shown in Figs. 3 and 4t, and a series of panel or tie bars 14:, T- shaped in cross-section, are introduced between the several uprights, the ends being made to rest upon the T irons or braces 12 of the standards.

One of the tie or panel bars is illustrated in detail in Fig. 5, from which it will be observed that a longitudinal slot 15 is cut in each extremityof the web-section b, which constitutes the horizontal member, and a transverse recess 16 is produced in the extremities of the head-section b, constituting the vertical member. hen the panel or tie bars are placed in position, their ends rest upon the brace-bars 12 of the standards A, as aforesaid. The inner members of the angled irons of the standards enter the slots 15, and that portion of the extremities in advance of the slots bears snugly against the side facesof the outer members of the standard angleirons, as illustrated at din Figs. 4 and 6, the base-wall of the recesses 16 being in a plane with the outer face of the standards.

In connection with the frame above described, I employ panels 17, which may be constructed of any desired material having a plain or an ornamental outer face, which panels, as shown in Fig. 2, are provided upon the outer face with a marginal rabbet 18, the rabbet at the sides being deeper than that at the ends, and in the rabbeted end surfaces a transverse groove 1.) is formed. These panels are placed in position in the following manner: The lower panel or tie bar 1a is seated between two of the standards A, and a panel is introduced between the standards and slid down until the rabbeted lower side edge is passed to the rear of the outer memher I) of the tie-bar, and said edge rests upon the horizontal or shank member I) of the same, whereupon the upper wall of the lower rabbet contacts with the upper edge of the member Z) of the said tie-bar, as shown in Fig. 3, and, as the rabbet is of a depth equal to the thickness of the member I), the outer face of said member and the outer face of the panel will be flush. The width of the panels is such that they contact with the opposed side faces of the outer members of the standard angle-irons. The next tie-bar is now placed in position and the upper rabbeted edge of the panel clamped thereon, and this operation is repeated until all the panels have been placed in position, the ceiling and cor nice forming a tie-plate for the upper edge of the upper panels. It is now necessary to tie the ends of the panels to place, and this is accomplished through the medium of a perpen dicular face-plate 20, a portion of which is illustrated in detail in Fig. 5. The faceplate is of a width equal to the space intervening between the opposed walls of the recesses 16 in the horizontally-aligning tie-bars 14, and said plate is provided with an inner flange 21 upon the sides, which flanges are provided with recesses 22, spaced to correspond with the distance between the vertical series of panel or tie bars. The perpendicir lar face-plates are made to cover the outer side edges of the several pairs of standard angle-irons, the flanges 21 entering the grooves 19 of the panels, and the recessed portions22 the recessed surfaces 16 of the panel or tie bars, and the face-plate of each standard is connected and held in position by screwbolts 24, which pass from one face of the partition to the other between the several pairs of angleirons 10 and 11, as best shown in Figs. 4 and 6. \Vhen the partition has been completed, as above described, the outer face is perfectly smooth if plain panels are employed, as shown in Fig. 1,which clearly illustrates the application of the partition to a large" room, whereby it is subdivided.

In Figs. 7, 8, and 9, I have illustrated a slightly modified construction, especially adapted for use in connection with ornamental panels. The departure consists, principally, in the formation of the standards and face-plates. The standards are composed of a single metal beam, substantially of girder shape, as shown at 25 in Fig. 9, the said standards having integral with their front and rear faces a longitudinal rib 26, and

plates 27 secured to the side faces to support the panel tie-bars,which plates 27 correspond with the T-braces 12. The recesses 1b in the panel or tie bars it are made to extend farther back than shown in Fig. 5, and the outer face is ornamental. The face-plates are made in sections-namely, a series of straight sections 1) and cross-shaped sections D, the cross-shaped sections D being located where the corners of the panels approach, as shown in Fig. 7, and the straight sectionsin contact with and above and below the top and bottom members of the cross. The face-plates are secured to the ribs 26 of the standards by means of screws 28 or equivalent fastening devices.

Having thus described my invention, I claim n ew and desire to secure by Letters 1atent 1. In a portable partition, the combination, with standards provided with attached transverse bearing-bars at intervals in their length, of transverse tie or panel bars essentially T-shaped in cross-section, contacting with the several standards and supported by the said bearing-bars, substantially as shown and described, whereby a series of spaces is formed for the reception of the panels, substantially as shown and described.

2. In a portable partition, the combination, with a series of standards and horizontal bearing-bars secured to the standards at intervals in their length, of a series of panel or tie bars contacting with the standards and supported by the said bearing-bars, which tie or panel bars are essentially T-shaped in cross-section, and perpendicular face-plates secured to the faces of the standards, which face-plates are rabbeted in the extremities of the tie or panel bars, substantially as shown and described.

In a portable partition, the combination, with perpendicular standards comprising pairs of angle-irons united by essentially T- ICC shaped bearing-bars, of a series of panel or tic bars T-shaped in crosssection, provided withtransverse recessesin the outer face at the extremities, which tie or panel bars are sup ported by the said connecting-bars, and perpendicular face-plates secured to the outer faces of the standards and filling the recesses in the tie or panel bars, substantially as shown and described, whereby the outer faces of the partition are straight and smooth, as specified.

4. In a portable partition, the combination, with a series of standards comprising pairs of angle-irons, and essentially T-shaped bearing-bars uniting the opposed pairs of angleirons and arranged at intervals in the length of said angle-irons, of a series of transverse tie or panel bars T-shaped in cross-section, provided with a slot in the extremities of the horizontal member, and having each extremity of the vertical member provided with a transverse recess, and face-plates provided with side flanges recessed at intervals, the said face-plates being secured to the outer with a transverse recess, face-plates provided with side flanges recessed at intervals, the L5- said face-plates being secured to the outer edges of the standards, covering the recesses in the tie or panel bars, and panels having a marginal rabbet securely held between the opposed standards, tie-plates, and face-plates, 20

substantially as and for the purpose specified.
